Johan - Paracord works pretty well.
Inksoup - Sure you can deffinatley make a heavier bow with this. I plan on bow fishing with one of these due to the "waterproofness" of the bow. It is also good for stumping, birding and walking around in the woods because you can make these shorter than a wooden bow. The only bad thing that I can think of is... the fact that its PVC and not wood. For us "purists"
Anyways the reasoning behind a youth bow build along is that PVC has many benefits for our careless, and developing youngsters like...
#1 Its cheaper to make!!!
#2 Its more durable and kids don't take care of bows as much as we do.
#3 It takes less time to make then a wood bow.
#4 It can be grown into. As the kids draw gets longer the bow can easily take that extra stress
#5 If you ever need to or would like to adjust the tiller it only takes a couple minuets to heat a limb.
#6 unlike wood if it is overstressed it is only gong to collapse and bend Vs. exploding and hurting someone.
So to put it simply its... Cheep, Safe, Time saving Fun and to me that screams YOUTH BOW!
PS you can always make these into take down's too!
