Jamie, you've got the exact opposite problem to me, with your tidy bowling attack and comparatively weak batting, which should make our friendly even more interesting.
I'd drop Kealey down to No.7/8 for the time being, as currently he's not that much better than the bats immediately behind him, and he's already down to Invigorated with his training. So if you want to get the best out of his bowling, you really want him to bat as infrequently as possible.
I don't know what your financial situation's like, but I'd really think about getting a No.3 rock in. around whom to base the rest of the batting. How about that O'Brien guy Scaly's got on the market - £1.3M sound's like a bargain to me, I'd bid myself if I had the money.
With regards to the opening situation, I'd persist with Kerwin for the time being, although he's not a long-term answer. You could partner him with Gowshall with his Prof Conc, but if you were worried about the defensive temperament, (which I don't necessarily think is a problem), you could recall Sugden, and take the bowling duties away from Aldred, allowing him to open. I'd certainly do this on more benign pitches, as you want Attacking Aldred to fill his boots at the top of the order, and because the pitch is more batter-friendly, you're not really going to get the most out of his two levels of Cons over Sugden in any case. Plus I think that Mccammon is pretty much just making up the numbers at No.8. He's not really good enough to bat any higher, and he's not really going to do all that much more than Sugden with the bat from No.8.
So In brief, I'd try and do something like the following:
1. Dom Kerwin
2. Maurice Aldred
3. Steven O'Brien (Or Similar)
4. Hamid Gowshall
5. Andrew Lea *
6. Dirk Wanless+
7. Dwight Kealey (b3)
8. Kevin Sugden (B4)
9. Anthony Fitzpatrick (b2)
10. Gareth Bardle (b1)
11. Daniel Laws (b5)[b]
Obviously Kealey will move up the order in time, and on tougher batting strips I'd bowl Aldred, drop Sugden, and recall either Jlloyd Ndah* or Dom Mccammon (Though I'd be inclined to flog Mccammon while he's still young enough to fetch some cash for you to put towards your O'Brien-style No.3.
Hope this helps, Trev
