Sig Riser Help
 

This is my first post on the sailplane forum, as I just purchased a Sig Riser kit. I have flown R/C and C/L for about 40 years but never giders. I chose the Riser for a trainer and relaxing sport flying.
After reading the Old Buzzard Soaring Book, the author did not have much good to say about balanced vertical fins which the Riser has. It is simple to modify the fin to a regular configuration. My question- Is it worth changing or is it no big thing to keep the balanced fin?
Also any opinions about adding the optional spoiler if I'm not planning spot landings
Any other suggestions about building the Riser would be greatly appreciated
Thank, Jerry Bohn
