John
Ive had the Shaky for two seasons now no problems, in my opinion its finished better than the sparton

ive used both.
I was going to buy a sparton now glad i saved the extra money to spend on other fishing stuff.
The sparton material i slightly tougher/stiffer than the shaky, but ive hooked my float tubes arms a number of times

i fish barbless so pretty easy to get them out

never had a punture remember if you fish "barbed" simply cut your line leave the fly till you are ashore, that way you wont punture your tube whilst struggling with it.
Hope that helps ................
