I am going thru same questions, I am getting ready to buy some new packs. i do not have any SMH's or HV's. I was thinking of buying like 2 or 3 SMH's and 1 HV just to see what it is like. I am hearing SMH's are the way to go though for TC's. Anyhow looks as if Schumacher showed well at Snowbirds. Congrats to all the Schuie drivers!!
