ISSA - International Slalom Skateboarding Association

So me and my friend have wanted to get into slalom for a while. Me I have been in the DH scene, but want to try slalom-ing.
I have a Sketch drawn to give to a custom builder because the only other deck I like is the Fullbag Louis Ricard and I cant find that one anywhere.(If you have it for sale Lemme know)
I aim for the custom board to look like http://www.silverfishlongboarding.com/f ... 1356892661 Its the first board I actually liked.
Specs of my custom board (estimate) and Questions.
Length:32-34
Width:9 at front, then taper to 8.3 then back to 8.7 at tail. (I don't have much understanding so feedback would be great on this topic)
Wedge on the tail: ????????
Do I use Coarse griptape?
Trucks: front :Bennett 4.3 Back: Tracker Rt-s
wedging:??????
Wheels: ??????
Bushings: many people reccomend reflex for Bennett and chubbies/eliminators for RT-s
Wheelbases:???
I guess I want to partake in HS and GS ? but want to fiddle around with straight DH.
Thank you for reading and please help me out!

Austin, if you can't find the Louis Ricard in any shop, it is available on our website right now. But the shipping address as to be in North America.

Coarse griptape: go for it.
Front truck: Bennett 4.3 with 5° to 10° wedging.
Rear truck: Tracker RTS 106mm with 20° dewedging is a good start on the Ricard.
Wheels: 70mm Zigs or 69 mm Hot Spots
Bushings: you have it right.
Wheelbases: 19.75" - 20.25" - 21" on the Ricard will fit whatever you want to do.
