I purchased the KTM bag because it fit reasonably well and the price was right. After using it for a couple of seasons the following is apparent to me:
1. It's construction is OK, not great but OK. Leaks water like a sieve (cover comes with it).
2. It is big. Good to hold alot of junk, but also big enough to get in the way (some).
3. I figure if I were to do it again it would likely be the waterproof Wolfman bag. Better built, water-proof, and somewhat smaller. More money too. Creeper might chime in here. I know Eric sent him one to try and I think he likes it.
