I think the 14 jumper is critical as well with this pack.
I was of firm belief Latu gets it but now I am leaning towards TDS.
Api gets gassed every week.
I would suggest at the 25-30 minute mark. Pole, Hunt & TDS. Bend the line, quick play the balls & TDS out of acting half.
Twal needs to be on at this point as well to hold the central defence.
Start - May, Klemmer, Api & Seyfarth (he is the starting lock for me at the moment)
25-30 mins - Hunt, Pole, TDS & Twal
Second half - Api & May back on form TDS & Hunt round the 55-60 minute mark
Klemmer & Seyfarth for the last 10 minutes for effort.
That's 8 interchanges.
