I definitely applaud your creativity and ability to retro-fit a fishing/hiking backpack into a dg bag. I can't help but to think that there comes a point when a bag that is not engineered to be a dg bag will eventually reach it's limitations in functioning as a dg bag. IMO it would cause someone to spend more energy trying to constantly 'make it work', than just enjoying a bag that is designed and created for dg. Counter productive is probably the easiest (maybe not the best) way to say it.
I can put discs in ANY kind of bag (grocery, backpack, pillowcase...yes i've seen it), and yes, it will work! But at what put is the hassle of trying to make something work (because you can save money) for something other than it was designed for wind up being just a big pain in the...
Let me reiterate, really love the creativity and the thinking out of the box:thmbup:, but something in me makes me wonder if this is really going to work GREAT for you (and not make you spend any unnecessary energy out on the course i.e. does the bag sit up perfectly on any kind of angle and incline or will you have to spend a couple of seconds trying to find the best way to get it to sit up, does the bag have a yoke system to distribute the weight of your gear properly, does the retro disc compartment allow you to put your disc back w/ out using two hands or trying to hit the 'perfect angle' into the compartment and in a matter of a second so that you can move on to your next shot? Those are the kind of things that could distract me or cause unnecessary physical/emotional/mental energy to be spent on my bag and not where it needs to be which is on the course.:thmbup:
