i would go with others and really question what kind of coach you having that doesn‘t know the basic difference of offensive play?
viscaria and hl5 are so completely different that you would only switch if you really want to change your entire game, as the others already pointed out. seams like your coach has no clue what playing style you have and just want to put you any racket in your hand, but that really doesn’t match with your rating. there you would have a complete playstyle already and really rarely change so dramatic, only when the coach thinks it is worth, but then it would be a really thoughtful process.
i think your coach just want to squeeze some money out of you, better stay with your equipment and concentrate on tactics (maybe change coach too)
