Poles vs tie outs for wind, snow, or rain

[navbutler]

Does anyone have experience or a link to a resource covering the advantages/disadvantages of some of the different types of winter tarp configurations such as internal end poles, external poles, center poles, or tie outs (UGQ and Dutchware both have examples). I would think that there are advantages to each type of system depending on the condition; heavy snow, driving rain, severe wind. Thanks
