lots of easy throw nets on ebay.
the seller stores have every net made to man
the sky is the limit to how high you want to go
good luck... I moved from a 5' to 8' using the same techniques I watched on here. I use the right handed finger drape method as opposed to the over the shoulder bite in your mouth fling... works well for me and my 12 and 13 year old boys. We learned in a couple of throws
I use about the same technigue throwing a cast net and was shown how by Dreadnaught who is a member on here also. I like the 10' size which is the largest you're allowed to use here in Ohio.
