Not wanting to be a killjoy but I have to say that if $50 at todays rate is about £25
Either the materials are being given away free in the States and you are willing to work well below minimum wage or I am missing something
Pins straps are made from good quality materials and I think are good value at the price he sells them
Althought I can't speak for Pin I know that the threads I use for anything structural is very strong (will literaly remove your finger before it breaks in a tug of war) and the webbing I use can tow a car (I have done it once in an emergency) these materials don't come cheap (you can buy cheaper but I won't) because someone could hurt themselves badly if they fail
The tyres for tyre socks can work out cheap if you buy bulk but buy too cheap and they will last one bocking session (I made one out of a £5 chinese tyre and it was through in less than an hour
When you tape springs it is for protection thin tape looks nice but the thick stuff protects better and as with all quality is dearer
Please don't take this the wrong way zendalfire I hope you can supply all you say at this price and keep the post costs down but remember if the parts don't last you won't get repeat orders and you only get one shot in this community as it is so small every one knows straight away if something is good or bad and posts accordingly
And yes that was naughty calling them (pinstraps)
and I wouldn't like to be on your end if he spots it
Having said all that I wish you the best of luck as we need things like this to make the sport more accesable but remember people will pay a little more if the quality is there
