Mega Tree Pixel Strings

Hi All,
Im building my first Mega Tree and are going to order custom strings from - possibly Ray Wu. Planning for 63 Pixels x 20 strings, 140 degree Tree, 5Volts running at 50% intensity Power Injection at bottom every string with T splitters. Also Im planing on using mainly square nodes but Bullet nodes just for the top 3 pixels so the strips can be a tighter fit on the Topper Ring.
Does this all sound doable?

Now the main question, whats better or easier to use, 20 strings (63lights) with pigtails on both ends
OR 10 strings (126lights) with pigtails both ends?.
Any help would be great!

Cheers
Stephan

don't over think the square/bullet things, my tree is all square and the top is 32mm apart and looks ok .. consider a bigger topper ring instead...I'd go for 20 strings at 63 and put plugs both ends. Make them all the same, it allows for easy swap out if a pixel dies ( plan a spare string) also consider the cost and time to make custom strings.
Cheers

Thanks Fing, Im building my own Topper based on the 48 hole steel version from Boscoyo, but a bit smaller, mine will be 11" (28cm) in diameter. Trying to get it as small as possible for the tree look and will be growing the string count in the future.
