Here, let's see if I can make this useful:
1st, if you have a Viscaria, you probably don't "need" any other blade. It is an awesome blade.
2nd, it's your birthday or Xmas or whatever holiday you want it to be for. If you want it, go for it! Have fun doing a little EJing.
If you like having fun trying different equipment, try away. At some point your wallet may take issue with you. But if you can afford this and it makes you happy, no reason to worry about it.
If money is an issue, you already have one of the best blades Butterfly has ever designed.
Top ply of Viscaria = Koto, which is crisp and on the hard side and good for highly skilled players who have excellent technique. For players who already know how to hold the ball on the blade face to get massive spin.
Top ply of MJ SZLC = Limba, which is softer, slower, has better dwell time and makes it easier to generate spin. However the SZLC makes this blade fast despite the top ply being softer and less crisp.
Neither of these blades are the best for someone trying to develop more spin and better technique. But if the technique is there, they are pretty great.
Personally, if I was going for a MJ blade, I would actually go for the MJ ZLC not the SZLC. The regular is more than enough juice. The ZLC should be very comparable in speed to the Viscaria with a slightly softer feel. Whereas the SZLC should be faster and, as you get further from the table, a little harder to control than the ZLC or the Viscaria.
What is your level America? How long have you been playing? How well do you loop vs backspin?
The answers to those questions would help to determine how well suited either blade would be for your development. But may have nothing to do with what you want or what will make you happy which can also be important factors.
