Not a bad team you named there. I reckon Brian Roche is rated slightly ahead of Meade by the management, so I'd be confident he would be picked. Eoin Roche didn't feature as much in the league, apparently he was (and maybe still is) injured, so not such an obvious choice. If O'Donoghue is fit he certainly starts, if not I'd say either Roche or O'Callaghan will get the nod.
Twomey has seen v little game time during the league (though he did have a decent Fitzgibbon), so would be a bit of a punt if selected. Personally I would have Dalton and either Twomey or O'Mahony on the wings. Dalton got a decent amount of game time so I would see him as a good bet to start if fit. However, based on league selections Ryan seems keen on Lehane and Kingston, so they might be included at the expense (from your team) probably of Power and Twomey.
So of the lads you named who you think might not make the cut, I'd be fairly confident that Dalton and Brian Roche will be selected, and I'd say at least one of the other three will get in as well.
