I agree with Bishop on this...The choice is yours...and Sunskin ain't the Best Coil Machines out there, maybe the best you have used, so just like picking a Rotary Machine it all comes down to experience...As you have limited experience, anything that is suggested to you could be futile, and pointless...Just go for the Spektra, with all available Cams/Motorbolts...It might not suit you, but will be easier to trade/sell than the Primus..
