You get more if you use FWC segments instead of metal....I've gone full Kerbal.
Boosters are two 5 segment SRBs, 4 GEM60XL boosters to help with TWR. 5 segment SRB as the center stage doesn't ignite until after the side boosters burn out. Second stage is famandy's second stage from the awesome Neptune launcher.
Total payload to LEO: 74,000 kg. More than FH.
But then it's just to much noise for the neighbours... ?Or I could just strap on some more boosters
