Just wanting a quick response here, as im busyingordering one.
I'm trying to decide between the 6' and 4.5' Halcyon dsmb. the cost differance is negliable, so i'm just wondering if theres any real reason why i should get the 4.5' one over the 6' one, is it alot harder to fill the 6', is the 1.5' so much of a differance to make it the choice.
thanks for any help

I have both and I only use the small one. The 6 is too hard to fill, needs to much gas to use it effectively and can't fit into a pocket (or at least not very well)
