I'm building an RC trailer. It's a dual axle setup, and I plan on using leaf springs. The deck is 21"x12" with a 3.5"x12" tipped ramp. I'm almost finished building the full aluminum frame and will be soon cutting the deck from some finished plywood paneling. I am making my own shackles as I find purchasing them a complete waste of money. Eight little simple pieces is not worth $40 in my book... But I do need some leaf springs. I don't want to make my own, as I want them to look scale and proper. I also need them to be stiff enough to support a 5-7lb trail truck (Depending on the truck). Adjustability would be nice also, meaning I can change the leaf stack as in taking one out or adding one. I prefer not to spend more than $30. Yes, I did look at the Juggernaut leaf springs, but I couldn't find them for or less than $30. If anyone can find some at that price, PLEASE post it. Here are some other ones I saw:

Spring D- http://www3.towerhobbies.com/cgi-bin...?&I=LXPMH4&P=M
I'm not sure if Spring E is supposed to be used or not. It's not listed in the Hi-Lift manual.

Ok, after searching here I did see some cheap shackles that might be worth the investment, I still might try making my own first.
I was hoping to get some info on how stiff each set is with which stack, what people think of the quality, which ones are thicker/better, what people think will work best, etc. Kind of like an open vote. I really like the price of the Sawback ones and how available they are, but I'm not sure if they are thick enough to be stiff enough. From the image I thought they looked thin. I'm also planning to run a decent speed, maybe 5-8mph. After reading, it sounds as if stiffer suspension is better for high speeds...
What do you guys think?
