so looks like i'll go for the 3/8 cdi as for higher torque figures i have a basic clicker 1/2 which is sufficient for subframe bolts etc that don't need super precision. if i ever need to work on valvetrain where high precision low torque figures are needed i guess i'll buy the 1/4 one in the future. for now my cheap ass is working on a budget and though i'd love all the pro tools in the world as any handy person does, it would nearly double the cost of doing a rod bearing if i go tool nuts for the job, so i'll stay disciplined and get what i need
