If the new blades 98's are an improvement to the previous, I don't think you can go wrong.
I've hit with both BLX blades - 93 & 98 & felt the 93 was too demanding for my level - good control & feel but very low powered & the weight got to be too much for me after a while. If you're a 4.5 or higher, it may be a non-issue.
Sorry DB but I don't have any feedback on the new line though.
