It depends on the drive, many prefer +r, such as NEC's and possibly your drive. Others will no doubt comment. I always use +r's anyway, very rarely -r, andnot for my own collection.
Genuine TY are hard to beat (there may be dud batches but this is very rare indeed) - most people will always suggest TY Dye media over any other - and when they suggest the like's of Verbatum, maybe that will be Pastels (TY).
Also, it's best to burn media at or just below it's rating.
