Im like 6ft tall and i just bought a 148 Sub Pop Snowboard.?

Mainly i do rails and jibs, a little jumping. I bought a 157 last year and hated how big it was so this year i bought a 148. Does that sound too small? I do a little all around mountain but mostly jibbing, like any rider i do trail riding too but no backwoods or anything. What do you guys thinjk
