Thanks for your sharing your experience/likes/dislikes/thoughts/repairs. It was interesting to see that photo of your specific pole tip (repeated below for reference), as it looks quite similar to the tips of one other fellow that contacted me about peak damage.
Indeed trekking pole tips are quite variable and it is difficult to have an interface that works with all of them (obviously we are paying close attention to this and will revise it to be more widely compatible in the future). What I'm seeing from users is that that a good portion of trekking poles don't substantially pressure the peaks (like those at the top left). Users with short tips like that are seemingly better off not to add rubbers grommets, since there is no risk of damage and the pole might pop out of the grommet if the opening is reduced. Users with moderately long tips (top right) will notice a small bump on the tent fly but I've tested this a lot since and I've talked with a lot of users and no one is finding this level of protrusion leads to damage because it doesn't stress the fly material to the point of tearing, and the black 210D nylon is tough enough to handle the pressure/abrasion. These people can alleviate the pressure with rubber grommets but there's no recorded damage/failures if they don't. Quite a few people with tips like these are reporting no damage after >50 nights.
Then the third group are poles with tips that are quite long (below left). These tips still don't damage the 210D black reinforcement, but they can split the fly material on top of that because the fly material has less stretch than the reinforcement. So the black material stretches over the protruding tip while the outer green material can't. These users would certainly benefit from using the rubber grommets, or diffferent poles, or pitching handles up.
With regard to other comments, I was quite conservative when fitting the inner tent inside the fly with the X-Mid 1P because I wanted to make sure it would stay protected inside the doorways (from falling rain) and not touch the ends/sides. After a lot more usage, I think it's is safe to make the inner a bit larger (5cm wider, taller and longer) in the future (at the cost of a few grams), and also add attachments so the inner can clip to the fly at the door tie outs to pull it out for more shoulder room (users can do this now - it just barely reaches). So that will add some more space, but changing the shape of major components of the tent requires a lot of prototyping/R&D though, so I'm not sure how soon I can do that.
I'll also encourage users to get in touch with Drop customer service if they do have damage to their tents that they think is falls within the warranty. Warranty is Drop's jurisdiction so I can't speak for them to say what they will and won't cover, but they generally seem to be quite helpful for the type of issues reported here, such as peak damage and holes in the mesh.
For the holes in the mesh, obviously it's hard to know what may have caused this. Perhaps it was a mishap at the factory. Another possibility is sparks from a fire. Similarly, the damage to the cord sheathing may have arose for various reasons. A common culprit is a stray blow while pounding in the stake with a rock, but I am sure there are other ways that it could happen. Holes in the mesh and damage to the cord sheathing are not widely reported, so I suspect these are more isolated examples from a mishap at the factory or subsequently.
One further topic that's not mentioned here, but can be a source of damage to the tent is improper tension on the inner tent. The tension on the inner is adjustable at the peaks. If someone adjusts the inner too high (so the tent floor is floating substantially) and then jumps in, that can put a lot of weight on the mesh which can tear the mesh or stitching. Normally it is best to have the inner adjusted closer to the looser end of its range for a bit wider floor but lower height. But is does depend on how high the fly is pitched. If the fly is pitched really close to the ground (and thus lower at the peaks) then there is room to pull it tighter.
So to sum up best practices for using the tent:
1) Ensure the inner isn't adjusted too high at the peaks
2) Ensure pole tips are compatible. If not, add rubber grommets or pitch handles up.
3) Use a groundsheet if the terrain may be abrasive/sharp.
Thanks again for your sharing your experiences and feedback. I'm glad you are enjoying the simplicity, and weather worthiness of the tent.
