Spurless climbing Western Red cedars can be really challenging. In the lower half of the larger ones, the branches slope downward, so to put a climbing line over a branch to climb into the canopy is hard because it wants to slide off the branch. They also tend to be thick so shooting a throwline into it can try your patience.
Concise, but comprehensive for a single paragraph on the subject. Hahahahh! Last time I tried to line-set (using big shot & hand-throws) for a spurless climb into a dense, unpruned cedar:
After an hour I got so fed up that I threw my 30' lanyard up around a "fan's flare"-shaped clump of sloped limbs about 12' up, threaded it back down through the pell-mell snarl of low candelabra branches (using a pole as my needle). It's like staring into the tentacled maw of a frozen kraken.
Then I used alt-lanyard technique to achieve a desirable TIP. Did not achieve the fast-climb time I was going for, though :/ Not even close. But that cedar was 50% worse. Even w/out ivy.
Now for this customer's cedar, I feel ya on your suggestion, RBTree; I was considering to use big-shot, try to get the claw game to grab a stuffed animal prize, & go SRT. But w/ all this ivy & limited firing angles (shooting underneath is a no-go; too much visual snarl), I might hand-lob or pole-set a line on an anomalously low, level, lateral limb (it's kinda visible in one of the pics) I discovered on the backside, then alt-lanyard &/or throwline my way to the top. I absolutely adore these trees. ^_^
I'm anticipating perhaps as high as a 50% slowdown rate for getting through the ivy at the first 50% of the tree's height w/out reducing safety. It's a real snarl up there, but I think I'll be faster than that. Here's hopin'.
