Uwe , Two very different boards . Thruster 5'11 = playful bump and jump , all round fun surfboard , knee high to overhead waves - great for beginner through slasher type rider - strapped or strapless. Signature 6'0 Quad = Super light , one of my favorite boards for down the line point break set up ....

Here goes Mark ,
