Get RB's or if you want an S3 piston/sleeve you can order from Europe. Not for being on the pants of Big Ernie or Trinity, but the performance of an S3 set is slightly more than their S1 counterpart and their durability and hold a little more temperature.
Many European hobby shops carry them and are about 100 Euros the complete set (with conrod) and if you substract the VAT can less expensive.
BTW: I don't know why people say that the S3 sleeve piston don't work with S1 units (are identical), so if someone has a S1 version you can upgrade simply swapping parts.
