cobra black utility / sz hybrid hosel width.

[Herts JoaTMoN]

Hopefully a quick one... I have a one length adjustable sz 4-5 hybrid and a one length black 4 utility I will be trialing for a spot in my bag. I also have a bunch of 7 iron fitting shafts I picked up really cheap (about £3 per shaft), a few of which i want to trial in these clubs.

I know they use the same size adapter as each other as I can change the shafts between these clubs and I am assuming that they are 0.370, but before i buy a few extra adapters for these, can anyone confirm if that assumption is correct? They will take weeks to arrive from abroad and id like to have the shafts ready to try when the driving ranges open again in a months time in the UK (if the rumors are true).

Note: I had an extra slot in my bag and thought one of these would be a good safety shot club for narrow fairways, troublesome lies or high wind conditions and want a combination that will give me a low launch, low spin and a tight dispersion.
