I had a 9.8 and while it was well made and Canadian (eh?), I did have a number of issues with it. I had to completely tear it down and clean out the brake assembly multiple times when it started slipping, It leaked air with the original seal head design, and the seat mounting flange eventually broke off the top of the post. I was also not impressed by the shipping cost for any of the small parts.
I have since gone to cartridge-based PNW droppers. Initial cost is lower, design is much simpler, and reliability has been much better. The only maintenance I have had to do is occasionally grease the top bushing. The loam lever is one of the best out there IMO.
