My experiences with SFS works were - are excellent,
had a banshee, great bit of kit,
have a phantom-even better,
Tony was a star to deal with,
triggers to both were excellent for me,
i have a stock 99 currently on loan to the nephew, he loves it, would i have it tuned, ,not before a 280 or others i have,
great little rifle etc,
also for me physically the 95 is a better fit, so a better option to start with,
no idea who Si is or seen any of his mentioned vids,
if i reviewed mine they would be described as the best i could afford at the time, and huge return on monies invested,
but it still seems like SFS is a little like marmite, lol, jmo,
