Im currently using all Lux ALU Rough. I used to use ALU Rough mains and a multi in the cross (X-cell, Premier softlex to name a couple) but that broke after about 5 weeks. I was wondering if using a synthetic gut cross would still be pretty durable. I was thinking of using Prince Top spin w/duraflex 15g. Would this be very durable and make the stringbed feel softer than using an all polyester job? Feel free to recommend other cross strings. Thanks.
