I've also noted that B2 clam to be "biger more powerfull" but the G powers are about the same (if not less)and cost more. I love the smaller ones. Now I have even beter reaion to 😀
I prefer Series 1&2 over the B2's too but what your typing is just downright inaccurate!Series 1 marbles had a range of 250G-450G in increments of 50 if you bought the American versions. Series 2 stepped that up to around 600 and added increments less than 50.B2 has a fair range that goes in increments of 10 form the 300's to the 700s!
