sure. actually, i too have had problems searching for some old threads lately.
someone had a good post on the spektrum bit about two or three months ago. it went something like this.
while spectrum offers the best response time by itself, it's repsonse time is in series with the response time of the standard radio, so it's actually a bit slower overall than not using it. however, it's on a level that is barely detectable, so i wouldn't worry much.
the hrs comment referred to equipment compatibility. the futaba hrs system will not properly operate an analog servo. so it's not so much a recommendation, as it is an instruction, from futaba. i think spectrum is ok with analog stuff though.
cost no issue, pick a top end, high speed, digital servo from any of the top manufacturers. sanwa and ko have the quickest out there at around .06sec. i personally like the short futaba 9550, but it is a bit slower than the others at .11sec.
