Ummmm, 'ang on; Triumph bigends are only .062" smaller than LG A10 ones at 1.625"
So if he's going smaller than .070" to fit Triumph rods, he's going way past the mark!

No he has the in between sizes too - not just the -0.070"!
I appreciate it would be weaker but at -0.070" it's still much bigger than the small journal crank - and I'm not likely to be holding it on the red line. Isn't someone here building a bike for the salt flats using Triumph T120 rods? - now there much smaller big ends and he'll be sure to be red lining it!

Ummm, yeah; thats me!
Triumph rod size would be fine, as I say, only 1/16" smaller.
But Musky's right, dont make it any smaller than necessary.
We're using triumph size because of the 89mm stroke crank - we're hoping to minimise crankcase clearance problems. The slightly smaller size buys us a bit more room.
No worries about strength as we're using a billet crank and rods.
