Well as I said earlier, use the slowest one (probably the Samsonov Alpha, or Cybershape Wood).
Of all blades mentioned, I know the Samsonov Alpha best.
It is a really good blade and one of the few that, depending on rubbers, can be your travel companion on the road to improvement ;-)
@FrenchFrog33
Take your Samsonov alpha and get rid of the K1 Hybrid rubber, but keep your FX-S.
Then take the correspondingly coloured FX-D from your Fortino and place it on the Alpha.
Find out which one you like better on FH and BH. Then stick to it.
If the rubbers wear off and you think you have practiced enough to want more power, take your R45 on your stronger side and if colours match pair with the other FX-D you still have left.
If all your rubbers are still fairly good you can use the first setup for 3 or 4 months and the second also with no need to spend any money.
Come Christmas, ask again what you should treat yourself with. ;-)
And, have fun practicing. You will improve.
