The Magellan gets poo-poo'd by many, but if you are a casual, weekend rec player and you want to spend 30 minuted and $10 with a hacksaw and some 1/2 CPVC - you'll end up with a fantastic backpack, that hangs with the $200 ones, for around $40.
I was on the fence for a LONG time. $200+ is a LOT of plastic, and a LOT of gas driving to new courses. $30 is what I spend on 2 discs at the store lol.
I do agree, on longer courses and days/weekends with multiple rounds it is a backsaver, and just generally more comfortable. I find that putting less strain on my right shoulder/neck while playing keeps me fresher and feeling better. There are some shorter pitch n putts nearby where I still use my crunch box - I tend to use the Magellan as a "master storage" bag, and for longer courses and double-rounds. I use my crunch box for a shorter, single round or when I'm focusing on 8-10 discs I want to dial in.
