I had tried to find the weights on the 2023 Lynx sleds vs. the 2023 Summits. Here it is, albeit not in time for spring order this year.
Summits are definitely lighter:
Shredder DS 3900 (154) x 2.5 850 E-TEC - 454 pounds Summit X 154 429 pounds
Shredder DS 3900 (154) x 3.0 850 E-TEC - 456 pounds Summit Expert 154 430 pounds
Shredder DS 3900 (154) x 3.0 850 E-TEC Turbo R - 476 pounds. Summit Expert 154 449 pounds
Shredder DS 4100 (165) x 3.0 850 E-TEC Turbo R - 480 pounds. Summit Expert 165 456 pounds
Shredder RE 3700 (146) x 2.5 850 E-TEC - 471 pounds Summit SP 146 447 pounds
Shredder RE 3900 (154) x 3.0 850 E-TEC Turbo R - 496 pounds Summit Expert 154 449 pounds
