Hi guys! What do you think about my LTD Mfb combo:
MF
Pegasus II
Spiral
90
Rf/R2f
?????

Do you advice me to change cw? And the best performance tips of the two? Rf has more stamina, R2f only cares about speed so the bey can hit harder...

Please use this thread for combo suggestions or advice on what parts to use, rather than make a new thread just to ask. Thank you.
