Já aprendi muita coisa sobre comandos mas queria ajuda de vocês na seguinte questão.
Gosto de torque em baixa, com a lenta girando redondinho, sem pipocação e sem trancos. Sei que o comando do 250-S é muito bom em baixa, podendo ser guiado devagarinho sem engasgar e embaralhar em baixa.
As especificações do 250-S são essas:
Modelo: Hidráulico - Flat Tapped
Faixa Básica de Rotação: 1.500 - 4.000 RPM
Duração Anunciada: 248º adm. / 258º esc.
Duração a .50 pol.: 192º adm. / 200º esc.
Levante de Válvula: 0.448º adm. / 0.460º esc.
Linha de Centro (Lobe): 112º
Estou procurando na Summit algo que seja melhor que esse mas que não comprometa em baixa. Qual dos três abaixo conservariam essa característica do 250-S e proporcionaria um pouco mais de potência?

A pergunta é: posso confiar nas informações prestadas no site da SUMMIT? Em tese os três teriam mais torque em baixa que o 250-S e ainda girariam mais. O que me dizem?
Muito obrigado a todos!
