Readspeed 5 Plate Centre spring?

Hello again Chaps
Euro prep going well and just gonna fit a 5 plate clutch, a mate has recommended using a CENTRE spring but I thought just using springs with the kit would be OK, the engines not making huge power Rapido Classic 225 30mll Dell and a Stealth exhaust but I will going over the Alps but NOT taking a pillion, I have never fitted a 5 plate or used a centre before just wondered if anyone had any experience/advice that would help....Cheers
